Sean Hannity sees his biggest ratings in years amid a wave of Trumpism

Sean Hannity. Getty Images Sean Hannity may have become the target for some critics in conservative media circles, but his ratings have rarely been better.

According to October Nielsen Media Group ratings, the longtime Fox News host's show "Hannity" had the largest ratings boost of any Fox News show all month, jumping 65% in total viewers from the previous month.

October was also one of Hannity's best month in years. According to Nilsen, the show's ratings were up 53% this month compared to the October 2013, when the show moved to the generally less-watched 10 p.m. timeslot.

Hannity's program also topped hosts Megyn Kelly and Bill O'Reilly on several evenings during the month, including shows on October 28, October 26, and October 25. In 2013, "Hannity" was bumped from 9 p.m. to 10 p.m., while Kelly took over his old time slot.

Hannity's ratings boost coincides with rising ratings overall for cable news networks as interest in the 2016 election has heated up, but also comes at an interesting moment for the longtime political commentator.

The television and radio host has emerged as one of the most high-profile boosters of Donald Trump, while the real-estate mogul has sparred repeatedly with other hosts at the network including Kelly and even occasionally with O'Reilly.

Hannity played a significant role in beating the drum for Trump, even if it occasionally raised eyebrows and garnered criticism from both sides.
